Liver-more 00., Allston, Mass a corporaj tion of Massachusetts Application Qctobe fm; 1933 No. 69435: g elaim g 9 45! 1 This invention relatestoalprotector-rod finger for looms particularly looms of a type having a either or both ends of the lay.

The object of the invention is to provideaprortector-rod finger of improved typeadapted-ito. engage the. shuttle binders in almanner toj' reduce the frictional resistance therebetween .when the boxes areraised'and lowered with theresult that there is an: easier. action on both the binders and;

finger as they move into and out of eng ement;

Fig. '7 is a side elevation of another protectorrod finger embodying my invention.

Fig. 8 is a rear elevation of the protector-rod finger of Fig. 7 viewed from the left of said figure. Like numerals refer to like parts throughout the several views of the drawings. 1

In the drawings, referring particularly to Figs. 1 to 4 inclusive, I0 represents a lay and II represents a group of shuttle cells constituting a shuttle box of well-known form located adjacent to an end portion of said lay. The shuttle cells II have shuttles I2 located therein and binders I3 provided therefor adapted to contact with the shuttles I2 when the latter arelocated within the cells. A protector-rod I4 is mounted in bearings I5 provided thereforon the front of the lay ID. A protector rod finger I6, constituting my invention, is mounted at an end of the rod I4 adjacent to a bearing I5. A spring I! of wellknown form is provided for the rod I4 and acts to force the protector finger; I! toward the bindersLI3 101:, the. shuttle cells-:H'. A: dagger I8 of welleknown iormisrigldly attached tothe rod I4. The finger IG-c'omprises abody member I9 which is rigidly secured at its lower extremity to the protectorrod ll by meansof a set screw 20. The body member I! has a space 2| provided therein between. parallel side portionsIZ which are located adjacent to. the, upper extremity 'thereof andfinthis-speoe a roller 23 is mounted to. rotate upon arstud Il -which in turn is mounted in both :of the sidevportionsj 22. The roller 23 embodies therein a rigid bushing 25 constructed of suitableematerial,preferably metal, around the 1 circumference of which. is a flexible peripheral portion IS-"preferably constructed of rubber or equivalent materiahv Thev rollers, 23" engage the edgesand front iacesof the binders I3 during the upward and downward movements of the shuttle cells II, the roller 23 beingrotated by the various bindersduringi'its contacttherewith. The rear edges. 11 of the: side portions 22: of. the body member [:9 arerformed in such a manner that they may engage the edges and front faces of the binders [3 in a manner to actuate the finger I6 in the event that the rollers 23becomewom to such an extent: that they; do not themselves engage the binders.

The, general operation of the protector-rod finger'hereinbeiore specifically described is as follows :e-In'. the operation ot the loom the shuttle boxes are raised and lowered in a well-known manner to correctly position the bottom of each cell I I with the race plateof the lay in order that the various shuttles I! will be correctly positioned with respect to said lay- During this upward anddownward movement, the roller 23 will en-' the loom, when a shuttle I2 enters'a cell II-properly, the protector finger I6 will be pushed forwardly and the dagger I8 'willbe lowered, so that it will not be brought into operative engagement with certain instrumentalities not illustrated in the drawings, but well known'to those skilled in the art, and which are adapted to operate aship per handle for starting and stopping the loom. If, however, the shuttle does not enter the cell, the spring I! will keep the roll 23 of the protectorv finger I6 pressed against the binder and the dagger I8 will remain in a raised position so that as the lay moves forward it will engage the mechanism gage the surface of the binders :I3 with an easy V side portions 42 01? thearm'4ll.

therefrom is an arm .30, whichis pivotally secured to said body member by means of a pin 3|. Mounted between side portions 32 of the arm 3| is a roller 33 which is rotatably mounted upon a stud 34 in turn mounted in the side portions 32.'

A spring 35 is secured to the body member 29 and engages the upper portion'offthe' arm 30 in a manner to normally hold said arm against an abutment 36 provided upon the body member 29. A screw 31 is provided at the upper extremity of the body member 29 and constitutes an adjustable stop to limit the yielding movement of the arm toward the body member 29. In, this embodiment of theinvention, the roller. 33 is preferably constructed 'of metal, although .it may be constructed of rubber if it is so desired:

In Figs. 7 and 8still another modified embodiment of the invention is illustratedin which 38 represents a protector finger having a body member 39 embodied therein. An arm 40 is pivotally secured to the upperextremityof the body member 39 by meansof a pin 'and-said-arm hangs downwardly beside the body member and swings upon said pin. Mounted between side portions 42 of the arm 49 is=a. roller. 43 which is rotatably mounted upon a; stud in .turn mountedxin the A coil spring 45 is interposed between the body. member 39- and lower portion of the'arm .40 and acts to' normally hold the 1OWe1.'pOItiOIl ofsaid annagainst an abutment 46 provided upon the body member 39. In this embodiment of the invention the roller 43 is preferably'constructed of metal, but may be constructed of rubber if, itis so desired.

Each of the fingersYZB or .38 illustrated in Figs. 5 to 8 inclusive maybe attached to .the'protector rod l4 in lieu of the finger I6 if it is so desired, in

which event the rollers1wil11'function to reduce the frictional resistance between the binders and the fingers.

I claim: 1

1. A protector-rodfihger for shuttle binders comprising, in combination, a.body member, an

arm pivotally attached to said body member to yield relatively thereto, and a roller mounted upon said arm and adapted to yieldingly engage said binders.

2. A protector-rod finger for shuttle binders comprising, in combination, a body member, an arm pivotally attached thereto, a roller mounted upon said arm, and a spring interposed between the arm and body member and adapted to hold the roller in yielding engagement with said binders.

3. A protector-rod finger for shuttle binders comprising, in combination, a body member, an arm pivotally attached thereto at an intermediate point thereon and projecting upwardly therefrom, a roller mounted upon said arm, a spring interposed between the arm and body member and adapted to hold said roller in yielding engagement with said binders, and adjustable means to limit the yielding movement of said arm.

4. A protector-rod .finger for shuttle binders comprising, in combination, a body member, an arm pivotally attached thereto at an intermediate point thereon and projecting upwardly therefrom, a roller mounted upon said arm, a spring interposed between the arm and body member and adapted to hold said roller in yielding engagement with said binders, and adjustable means to limit the yielding movement of said arm, said arm having a surface embodied therein also adapted to engage the binders in the event of excessive reduction of the diameterofthe roller.

5. A protector-rod finger .for shuttle binders comprising, in combination, a body member, an arm pivotally attached thereto at the upper end thereof and hanging downwardly from said pivot, a. roller mounted upon said arm, and aspring interposed between the arm and body member and adapted to hold'the roller in yielding engagement with said binder.

6. A protector-rod finger ior the binders of a vertically shiftable shuttle box comprising, in combination, a body member, a horizontal axis member mounted thereon, and a roller carried by said axis member and yieldable relatively to said body member whereby said roller may have yielding rotative engagement with said binders during the shifting movement independent of any yielding action of the body member. v
